Abstract: Although a range of transition-metal-catalyzed cross-coupling reactions of alkenes and alkynes have been developed to produce valuable conjugated dienes, extension of these reactions to iridium catalysis has yet to be demonstrated. The first iridium-catalyzed alkene-alkyne… read more here.

Abstract: The greenhouse gas SF5CF3 acts as CF3 source for the photocatalytic trifluoromethylation of arenes on using [Ir(dtbbpy)(ppy)2]PF6 (4,4'-di-tert-butyl-2,2'-dipyridyl, ppy = 2-phenylpyridine) as catalyst. The trifluoromethylation of C6D6 in the presence of 1-octanol results in the… read more here.
